Onebook Portable Bathtub – Foldable Adult Spa Tub for Ice Bath and Hot Bath

Onebook Portable Bathtub: Foldable Spa Tub for Adults

Turn any bathroom into a private spa with the Onebook Portable Bathtub. This foldable tub fits in a shower stall or on a balcony, delivering a roomy, comfortable soaking space without the burden of a full-size tub. Built to travel with you, it combines durable materials with a thoughtful interior that makes setup simple and quick.

Roomy design and real-world versatility

At 45.3 inches long and 19 inches high, the tub offers a comfortable submersion for most adults. The six sturdy pillars form a stable frame that resists tipping, even when space is tight or the floor is uneven. When you need to move or store it, the tub folds down compactly for easy transport.

Weather-ready insulation and temperature range

Six-layer insulation with enhanced canvas cloth and thickened PVC pipes helps retain up to 85% of the water temperature for up to three hours, so you can linger in comfort. It tolerates a wide range of ambient conditions from -10°C to 50°C, and works from -4°F to 158°F for flexible use.

Hot bath and ice bath in one tub

Whether you crave a warming soak or an icy plunge, this tub adapts to your mood. The dual capability supports you in crafting varied routines, from steady warmth to refreshing cold exposure, without swapping equipment.

Stable, easy to assemble

Six pillars provide a solid base that supports larger body sizes. Assembly takes just a few minutes—no tools required—so you can begin your session quickly after unboxing. A thoughtful care routine helps keep the frame in good condition over time.

What’s included and practical setup tips

Your package includes a manual air pump, a drain pipe, a portable bag, a water-filled cushion, and clear instructions. For best stability and to protect the support tubes, fill the tub to about half before use.

Practical usage ideas

• Use after workouts for a relaxing or restorative soak, as time allows.
• Pair warm and cold sessions to complement your routine and mood.
• Store and transport with the included bag for flexible home spa moments.
